Study commercial learner's permit and CDL knowledge topics with CDL Permit Prep. The app's question bank contains 1,319 multiple-choice practice questions: 959 with national scope and 360 focused on state-specific topics. These are counts in the app, not the length or question count of any state's exam. Topics include General Knowledge, Air Brakes, Combination Vehicles, Hazmat, Tanker, Doubles/Triples, Passenger, School Bus, Hours of Service, and Pre-Trip Inspection. REVIEW QUESTIONS AND SOURCES Read an explanation after each answer and open its source reference. Study the federal topics and state-specific material included in the app, then check your state's current CDL manual and licensing-agency guidance for requirements that apply to you. PRACTICE YOUR PRE-TRIP CHECKS Use the trainer to identify vehicle components, describe the checks you would make, and explain safety concerns. Follow your state's current CDL manual and test instructions. The trainer does not require a script; examples are optional prompts, so use your own words. Trainer feedback is for practice and is not an official test score. STUDY BY CDL CLASS AND ENDORSEMENT Choose the class and topics you want to study. Review missed questions and practice the included CDL subjects at your own pace. Some CDL question translations are still under review and may appear in English with a notice. This app is study material, not an ELDT course and not a substitute for training required by FMCSA rules. Practice is not the exam. Check your state's current commercial driver handbook and official licensing-agency information. For support, visit https://cdlpermitprep.org/support. CDL Permit Prep is an independent study product and is not an official licensing-agency service.

Verdict

The call

The clearest difference is in-app purchases: CDL Permit Prep at none against CDL Pro's 3. CDL Permit Prep also leads on update cadence (every 4 days vs every 2 months). CDL Pro's advantage is ratings volume (8 vs 1) and iOS requirement (15.1 vs 26.0). On price, rating, ads and device support there is nothing between them.
